Abstract In this study, the histological structure of digestive system development of the larval and juvenile of rice flower carp Cyprinus carpio was observed by histological technique, and the changes in feeding selection and digestive enzyme activities were measured to explore the suitable weaning food for the larvae and juveniles of rice flower carp. The results showed that the larvae began to feed at 3 days old, and digestive enzyme activities were observed before feeding. At 5 days of age, the dental sac appeared, and chewing and digestive functions were enhanced; at 6 days of age, the striated border appeared in the digestive tract, which indicated the beginning of intestinal function of the larvae. At 8 days of age, the alkaline phosphatase activity was increased significantly, indicating that the intestine had developed well. And at this point, the hepatopancreas began to develop fully, lipase and amylase activities subsequently increased. At 10 days of age, the scales of larvae were observed for the first time, indicating that the larvae were transformed into juveniles. After 12 days of age, the nuclear contents and vacuoles appeared in the intestine, indicating that the intestinal protein digestion function was basically improved, and the activity of acid protease was increased. At 30 days of age, the morphology and function of digestive organ were close to that of adult fish. Before 14 days of age, it was speculated that small algae and rotifers were the main food sources; and after 14 days of age, the food intake of zooplankton increased significantly. The findings indicated that the feeding of the larvae and juveniles of rice flower carp were related to digestive organ development and digestive enzyme activity. The change in digestive enzyme activity after initial feeding was affected by the development of digestive organs. It was suggested that the particle size of the food be 50—170 μm in 3 to 14 days of age, and that the proportion of fat be increased in 10 to 14 days of age. At 14 to 30 days of age, the feeding habit of rice flower carp was omnivorous preference animal food type, it needed nutrition balanced compound feed (protein and fat) and mixed zooplankton feeding with size 170—350 μm in at this time.
